Most Helpful Positive Review Pretty cool upgrade
Bought this thinking it would be kinda difficult. Nope, very easy to work with and adjust. I put it in my .308 and have another in my 556. Haven't shot with it in yet. But I'm sure if it don't work right... I can always adjust it. Only complaint is, that the screw that holds the weights into the buf...

Most Helpful Negative Review Things need to be considered before buying
It's not that I didn't like the product. It's not that it isn't well made. It's not even that it's a bad idea. ODIN Works is one of the best companies in the industry and the concept is sound. There were some problems on my end that have made it, shall we say, not the best choice. Things you need t...

Very Nice buffer

by Stallwle, Verified Owner from GA, United States Written on November 18, 2025
bought this for a 12.5 suppressed build, nice part that has plenty of Adjustability for a 16" Carbine, but if you have something 12.5 or shorter and are going suppressed I would recommend going with the PCC model of this buffer. I had to steal an extra Tungsten weight from my PCC buffer to use in this AR Heavy buffer to get it to control the Bolt Bounce, even with a Adj gas block. Or you could just buy an extra Tungsten weight, or two, if needed. my only complaint is I wished they had included an additional rubber spacer or two incase you lose one.
Pros:
  • Quality
  • Fit and finish
  • lots of weight options
Cons:
  • extra spacers
  • one more Tungsten weight
Best Used for:
  • Suppressed SBR
  • High Rates of Fire
  • need for Adjustability
Would recommend: Yes

Extra noise

by Joe, Verified Owner from MI, United States Written on November 1, 2025
It's good for the intended purpose. However, it makes more noise than any other buffer when you're just moving the firearm around.
Pros:
  • Adjustability
Cons:
  • More noise than other buffers
Would recommend: No

Great for customizations and modifications

by Terry W, Verified Owner from TX, United States Written on October 7, 2025
This is great for making adjustments on the fly after a modification. I like the ability to set the weight while in the field testing. Even with a H, H2, and H3 with me, sometimes I need either weights in between or even more weight. For more weight you need to order Tungsten weights which it does not include.
